I will fix bugs in your lovable bolt replit base44 app supabase auth and rls
Rendy T
About this gig
Your AI built app works until it hits a real user.
Lovable, Bolt, Replit, Base44 and v0 ship fast, then leave
you with broken auth, exposed database rows and payments
that silently fail. I fix that.
I am a full stack developer with 8 years of production
experience. I currently maintain a live ecommerce platform
handling real money, real stock and 23,000+ transactions.
WHAT I FIX
- Supabase RLS policies that leak data between users
- Broken login, signup, session and role based access
- Payment webhooks that never verify signatures
- Duplicate orders from missing idempotency checks
- Database schema, relations and migration errors
- API and third party integration failures
- Runtime bugs, build errors and console warnings
WHAT YOU GET
A clear written diagnosis of what was actually wrong
The fix applied and tested, not patched over
A short note on what to watch for next
HOW IT WORKS
1 Send your repo or project link and the symptom
2 I reproduce it and confirm scope before you order
3 I fix, test and hand back with an explanation
Security work is not guesswork. Send me your error message
or screenshot and I will tell you honestly whether I can
fix it.

FAQ
Which builders do you work with?
Lovable, Bolt, Base44, Replit, v0, Cursor and Claude Code output. If your project is React or NextJS with Supabase, Postgres or MongoDB underneath, I can work with it regardless of what generated it.
Do I need to give you my database password or service role key?
No, and please do not send those in chat. Invite me to your Supabase project as a collaborator and give me read access to your repository. That is enough for me to diagnose and fix.
What if my app is too broken to fix?
I will tell you before you order. Send me the link first. Sometimes a rebuild costs less than a rescue, and I would rather say that upfront than take an order neither of us is happy with.
Will you break the features that currently work?
I work on a separate branch and hand you a pull request. Nothing touches your main branch until you review it. For live apps I test against a copy of your data, never production.
Can you add new features while you are in there?
That is a different scope. Message me and I will send a custom offer with its own price and timeline, so the fix you already paid for still lands on schedule.
